AGRICULTURAL IMPLEMENT.

Specification of Letters Patent.

Patented July 1., 1913.

Application filed October 24, 1911. Serial No. 656,435.

structions for producing an implement whichembodies a cultivator,fertilizer and seed planter.

The invention consists in certain details of construction andcombinations and arrange ments of parts as hereinafter described andmore particularly pointed out in the claims.

In the accompanying drawings I have illustrated one example of thephysical embodiment of my invention constructed ac-. cording to the bestmode I have so far devised for the practical application of theprinciples.

Figure 1 is a plan view of an implement embodying my invention. Fig. 2is a side elevation of Fig. 1 with the rear ground wheel removed forconvenience in illustrating. Fig. 3 is a transverse vertical section online 3-3, Fig. 2. Fig. 1 is an enlarged detail view of the clutchactuating mechanism.

In the preferred embodiment of my invention as illustrated in thedrawings the frame 1 is supported upon the axle or shaft 2 upon whichlatter are journaled the ground wheels 3. Located at the forward end ofthe frame is a smaller wheel or roller 4, journaled in the fork shank 5,which is adjustably secured in the sleeve 6, by means of the set screw 7in order that the wheel or roller 12 will lift the covering board fromthe ground and throw the board out of operative positlon, where it maybe held permanently by means of the pawl and rack mechanism 13. For thepurpose of lifting the covering board Sin order to pass overirregularities in the ground, or rocks, or other obstructions, I providea foot lever 14, which is fulcrumed at 15, to the extension 11 and hasits crossbar 16 in contact with the underside of the bracket arms 9. Theoperator sitting in the seat 17 may, when he desires to temporarilyelevate the covering board, by lifting pawl 13 and depressing thetreadle 18, lift the covering board 8 as will be understood.

For cultivating the ground it will be iinfurrow opener 20. The doubledisk cultivators 19 are for the purpose of re-opening the furrows andthe four disks 19, located at proper intervals each side of the centerof the implement, are for turning the soil, as will be understood, andthe plow 20 is for the purpose of opening the ground for theintroduction of the cotton seeds. The disks 19 and plow 20 are supportedas usual on the shanks 21,which are vertically adjustable in the sleeves22, formed integrally with the beams 23. There are live of these beams23 and the tools may be secured thereto in ad justed position by meansof the set screws 24. Each of these beams is provided with a bracket 25through which the rear rod 26 extends, for supporting the rear ends ofthe beams. The front ends of the beams are supported by means of the rod27, which passes through the perforated brackets 28 on the beams 23.

In addition to the adjusting means already described for the disks andplow which are furnished by the set screws 24 and by which the disks andplow may beadjusted independently of each other, I also provide means bywhich. all of the tools may be adjusted to different positions or thrownout of operation entirely. This operation is accomplished by means ofthe rock shaft 29, which is journaled in the bearings 80, carried by themain frame 1. The rock shaft may be moved by means of the lever 31 andby this movement the rocker arms 32, which are rigid with the rock shaft29, pull up on the links 33, which are connected to the bar 26 at therear of the beams 23. This action lifts the rear end of the beams, andthe forward ends of the beams are simultaneously lifted through themedium of the slotted cam arms 34 in connection with the forwardsupporting bar 27. The cam arms 34: are secured on the forward rock bar35 and this rock bar 35 is connected to the rear rock bar 29 by means ofthe rocker arm 36, draw rod 37 and rocker arm In this manner with thetools in position indicated in Fig. 2, when the lever 31 is pulled overtoward the rear of the implement, the beams and tools are bodily liftedfrom the ground, the cam arms 34 are turned on the rocker arm 35 as apivot and as the cross-bar 27 travels in the slots 38 of the arm 34, theparts will he lifted, and to guide the movement of the bar 27 I providethe slotted bracket arms 39, which are rigid with the frame 1 of theimplement.

Located near the front of the implement is the fertilizer distributor,which comprises a receptacle 40, having openings 4 1 in the bottomthereof, which communicate with the open spouts 42, which extend asuitable distance from the receptacle 4:0 toward the ground. Ipreferably employ guano as a fertilizer, and this material is stirred upand fed to the openings ll by means of the arms 43, carried by the shaft14, which extends through the lower portion of the receptacle 4-0, andhas at its outer end a sprocket wheel It will be observed that thestirring arms 43 are arranged on the shaft 44 in positions so that thematerial will be fed to the openings 41 in the bottom of the box orreceptacle d0. The flow of material through the openings 41 may beregulated and adjusted by means of the slidable plats or cut-offs as,which are formed with lugs 17 for the reception of the screw bars 48. Byreference to Fig, 3 this construction will be apparent and readilyunderstood.

The sprocket wheel 45 is rotated through the medium of the chain 49 andsprocket wheel-50 on the countershaft 51. And the countershaft 51 isrotated from the axle 2 by means of the chain 52 and sprocket wheels 53and 5 1.

The seed planter .comprises a receptacle 55 formed with an opening 56 inthe bottom thereof, through which the seeds are passed by means of thewheel 57, formed with spokes 58. This wheel is supported upon shaft 59which also has stirring arms 60 attached thereto. The shaft 59 isrotated from the countershaft 51 through the medium of sprocket chain 61and sprocket wheels 62 and 63.

I have so constructed and arranged the different parts of the implement,so that when the disks are elevated from operative position, the samemovement which accomplishes this action also throws out of operation themoving parts or mechanism of the implement. To attain this end I providethe rocker arm (it on the rock shaft 29 and this arm is connected by alink 65 to the link 66. The link 66 is pivoted to the plate 67 at oneend and the other end of said plate is pivoted at 68 to a collar 69,which is rotatable with reference to the clutch member 70, but immovablelaterally thereto. The clutch member 70 is adapted to engage thecomplementary member 71 integral with the sprocket wheel 54. The plate67 is provided with a slot 72, which is located so as to travel aroundthe fixed pivot 73. This pivot 73 is preferably a stud or pintleprojecting upwardly from the bracket 74, which is braced by means of thecross-bar 75, and at the other end is connected to the axle 2. Thus theforward movement of the lever 31, in lifting the plow beams and disksfrom the ground also, through the connections described, swings theslotted plate 67 on its pivot 70, and because of the location of theslot 72 and its relation to the fixed pivot 7 3, the movable pivot 68 isdrawn toward the observer in Fig. 1 and the clutch members 70 and 71disconnect-ed. Inasmuch as the clutch men iber 71 and sprocket wheel 54are loose on the axle, it will be understood that the disconnection ofthe clutch members will render the entire actuating mechanisminoperative.

It will be understood that the implement may be drawn by horse-powerattached by means of a double-tree to the eye 7 6 in the beam 77. Thedouble disks 19 for re-opening the furrow are located just in advance ofthe delivery spouts l2 for the guano, and the four listing disks followthe re-opening disks, and are spaced at regular and deter minedintervals. The plow 20 for opening the ground is located directly infront of the seeder and the seeds are dropped from the receptacle 55 inthe furrow made by the plow. The covering board 8 follows directly inthe path of the plow and dropped seeds, and performs the well-knownfunction of covering the dropped seeds and fertilizer.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:
